Noise from AC vent area question

[bobbychow305]

Hi gang. I noticed a humming noise when I change foot/head vents or any buttons to change vents. It's like humming sounds then goes away.
Also, there is no air on foot when I select foot air.

Could be the servo for your footwell vents going. It’s a common problem in the 4th gens. Give a search for that and you’ll find some threads on the issue and how to repair it. Luckily, driver’s side is easy; passenger’s, not so much.
My symptom was a “whirring/clicking” noise as the servo tried and failed to open my footwell vents. Sounds like maybe your servo is humming while trying to open the vent?

Yea- clean out your cabin filter. Otherwise, this is likely your answer DIY: Replace Servo Sub-Assy
